Three-nucleon bound states using realistic potential models -: art. no. 034004

The bound states of H-3 and He-3 have been calculated by using the Argonne v(18) plus the Urbana IX three-nucleon potential. The isospin T = 3/2 state have been included in the calculations as well as the n-p mass difference. The H-3-He-3 mass difference has been evaluated through the charge-dependent terms explicitly included in the two-body potential. The calculations have been performed using two different methods: the solution of the Faddeev equations in momentum space and the expansion on the correlated hyperspherical harmonic basis. The results are in agreement within 0.1% and can be used as benchmark tests. Results for the charge-dependent-Bonn interaction in conjunction with the Tucson-Melbourne three-nucleon force are also presented. It is shown that the H-3 and He-3 binding energy difference can be predicted model independently.
